Abstract: 854,754. Tuning resonant lines. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 10, 1957 [April 13, 1956], No. 11742/57. Class 40(8). [Also in Group XL(a)] An electron discharge device, preferably a velocity modulation tube in which the beam is subjected to multiple to and fro reflections, has means for producing rectilinear movement of a tuning element within the envelope comprising a lever pivoted at a point outside the envelope and extending through flexible bellows 18, and an annulus 13 and coupling member 12 in the linkage, the annulus 13 having a first arcuate rigid section 14 connected to the lever and a second arcuate flexible section 15 which is flexible perpendicular to the axis of the annulus and rigid in the tangential direction. The tuning member 7 preferably moves parallel to a tangent to the circular arc traced out by the end of control rod 16, and so alters the frequency of lecher line 4. The rod 7 has resilient contact strips at each end which slide along slits in the wall of box anode 3. Tuning rod 7 is connected by rod 10 to two quartz tubes 6 which slide over rods 11 not shown fixed to the anode 3 and are connected to bifurcated member 12 welded to ring 13. The ring 13 is connected to flexible bellows 18 by plug 17, 15 being a flexible half and 14 the rigid half of the annular ring 13. If flexible part 15 is made smaller than rigid part 14 the quartz tubes 6 are unnecessary since, it is stated, the bifurcated member 12 in this case moves rectilinearly.

Patent GB-274591-A (GB)
Title: Improvements in kinematograph and other colour films and methods of manufacture
IPC: G03C7/20
Filed: 1926-05-06
Abstract: 274,591. Thornton, J. E. May 6. 1926. Drawings to Specification. Colour photography; films and papers, stripping. - Raw material for the production of positive kinematograph films, strip or single photographs, lantern slides, window transparencies, &c. of the kind comprising a transparent waterproof support such as celluloid or glass carrying a ready-coloured sensitive colloid layer upon which is laid a temporary reinforcing layer of paper, and wherein the colloid layer is united on the one side to the support and on the other to the paper layer by an adhesive substratum, is manufactured in two parts which are cemented together to produce the finished material. In one method, the transparent support is coated first with a substratum and then with the colloid layer, and the paper is coated with a substratum, the two parts so produced being then united by moistening the colloid layer, or the substratum on the paper, and pressing the two parts into adhesive contact. In an alternative method, the colloid layer is coated on the substratumed paper instead of on the substratumed support, and the parts are united as in the first method. The substratum between the support and the colloid is an insoluble layer containing, for example, hardened gelatin, while that between the paper and the colloid is soluble, for example, a layer of soluble gelatin, so that when the material is developed to produce relief or non-relief images after exposure through the support, the colloid remains attached to the support, while the paper layer becomes detached and is discarded. Sensitizing is effected either by bichromate or other slow-printing salts, or by rapid printing silver salts, and the colouring- matter comprises either pigments or mordanted dyes or both. The back of the support may be coated with an anti-curling hardened gelatin layer united to the support by an insoluble substratum. For monochrome pictures, the material may be manufactured of single picture-width, or of double picture width one half of which carries the sensitized coloured colloid, and the other half plain unsensitized colloid, this half serving merely as a covering layer when the double-width material is severed, after printing, &c., and the two halves are cemented together. For multicolour pictures built up from two, three, or four colour components the material may be of single picture width for each component, or may be manufactured respectively of double, triple, or quadruple width carrying side-by-side areas of colloid coloured with the desired colours, and intended to be slit after printing &c. in order that the components may be cemented together. If the side-by-side areas of colloid on a multi-width film are coloured by applying dyes to the alreadycoated colloid, the areas are isolated from one another to prevent running of the dyes by narrow lines of hardened colloid produced by local application of a hardening solution. Specifications 214,934 and 224,571 are referred to.

Patent GB-892626-A (GB)
Title: An electric switching programme control device for clothes washing and dish washing machines
IPC: A47L15/46
Filed: 1958-04-16
Abstract: 892,626. Time switches. HOLZER, W. April 16, 1958 [April 20, 1957], No. 12114/58. Class 38 (5).  A programming device for washing machines comprises contacts 2 operable by cams 1 mounted on a shaft 3 controlled by an escapement mechanism 4, 5 driven by a store of potential energy which is recharged after each switching operation. A motor 8 drives a programme disc 6 via gearing 7, and a spring 10 couples the disc 6 to the shaft 3. Pins 9 and 26 on the disc 6 control the escapement member 5 as shown in Fig. 2. Rotation of disc 6 in the direction of the arrows 24 strains the spring 10 which causes wheel 4 to tend to rotate in the direction of the arrow thereon. Thus claw 14 is pressed upwardly and member 5 tends to lift a locking bar 16 by means of a pin 15 engaged in a slot 18, but a nose 20 on the bar 16 is held against a buffer 25 by spring 25A and prevents any movement. A projection 19 on the bar 16 is, however, in the path of pins 9 such that at a predetermined time a pin 9 will pivot bar 16 so that nose 20 is clear of buffer 25 and the bar 16 and member 5 will move to the positions shown by broken lines, allowing wheel 4, and hence shaft 3, to move one step. Claw 13 is then engaged by wheel 4 and tends to restore the member 5 and bar 16 to the full-line position which is not permitted until a predetermined time later when a pin 26 engages projection 19 and releases nose 20 from its position above buffer 25 allowing wheel 4 and shaft 3 to move a further step. In practice, the number of notches on wheel 4 is related to the number of pins on disc 6. A certain switch position may be set manually by rotation of a knob, not shown, which turns disc 6 such that pins 9 and 26 engage the projection 19 in relatively rapid succession allowing the escapement to run vertually continuously until the desired position is reached.
